lib: improve esm resolve performance #46652

anonrig · 2023-02-14T16:19:34Z

I couldn't find a benchmark or had the time to write it, but in theory, it should be a lot faster.

On quick glance this seems fine, but we need to land #44710 first. Just putting a hold on this until that gets landed.

lib/internal/modules/esm/resolve.js

I chatted with @anonrig and they offered to rebase #44710 on top of this if this is ready first, which seems fine to me. I’d still like to ensure this doesn’t slow down #44710 landing though; the rebased version of that branch shouldn’t have any new test failures.

I'd like to see a benchmark for this, but the theory looks solid. This can land before or after the off-thread PR, the conflicts should be minimal :)

Shouldn't it be factorized with the cjs/loader implementation (note that since it isn't in this PR, the esm implementation doesn't has a cache)?

I agree, but I prefer to do it in a different pull request, and keep this minimal.

Before we land this shouldn’t there be some attempt at confirming that this does, in fact, make things faster? And especially not slower. Even just running a benchmark on someone’s local machine.

To strengthen @GeoffreyBooth 's point
Making sure benchmarks are run in some form before this lands. Please dismiss my review when that happens @anonrig (or whomever)
